Everyone wants details...so here they are! The third video is a detailed overview of the Lexus LFA features. Take a look.

Nice car cover bag. Id use it for personal use and store the cover elsewhere.

Awesome videos.

edit: oh nevermind. Owners get fitted luggage. Looks nice.

Man o man! That silver looks amazing in the sunlight. People were criticizing the silver, but that has to be one of the best LFA colors. The shine is just incredible.

It would be nice to see a demonstration of launch control system.

The fitted luggage makes it all worth it. That's the real value proposition.

The redline limiter is pretty cool - I always get nervous when I see all these videos of people firing up LFAs and rev-ing them while seemingly cold. Actually, I realize now that one of the engineers was trying to explain the redline limiter to us at the end of the LFA Works tour but I was distracted by the noisy prototype and probably it got a little lost in translation too.

I'm going to go post "You're welcome" in response to Mark Templin's video later.

Wow that auto-adjusting redline limiter is awesome! Another typical hidden Lexus feature . Attention to detail is what it's all about. Auto-adjusting the redline based on coolant temperature and the car's break-in, such a good idea.

05RollaXRS

You know what the funny part is? My Toyota/Yamaha built 2ZZ-GE does the samething (though, no cool moving redline on the tacho). On a cold start, the rev limiter is set at 7000 rpm and VVTL-i is disabled (no 'high lift' cam switch over) it goes progressively up as the car gets warmed up until finally up to 8400 rpm when it is completely at the optimal operating temperature.

TRDFantasy

Very cool, I did not know that . Does it adjust based on the car's break-in period as well?

05RollaXRS

Actually, I took it 8400 rpm a few times with just a couple of hundred KMs on it so during the break in period (I broke it in quite hard), there was no such limitation.

However, in the case of Lexus LFA, it is totally understandable since it is such an expensive engine to build .

TRDFantasy

It is understandable, and it is also awesome IMO that the LFA as a car is that intelligent that it adjusts the redline based on both coolant temperature and break-in period. It's touches like that which make a Lexus a Lexus, and it's quite awesome to see that in an exotic supercar. Then again, exotic supercar or not, it's still a Lexus, so it is great to see it is totally built to high Lexus standards.

05RollaXRS

Yeah, LFA is capable of revving up to 9500 rpm. That is stratospheric to the point of almost a race car. It totally makes sense to have a adjusting rev limiter based on the breaking in period.

TF109B

What race cars even rev that high? Not many!

TRDFantasy

Depending on what racing series we're talking about, some do, but you're right, not many. In Super GT, I believe no cars rev beyond 9000 RPM, AFAIK.

In Le Mans, I don't think any cars rev beyond 9K RPM, but again I might be wrong.

F1 obviously revs higher. In WRC, I'm not sure how high the highest-revving cars go to.

In NASCAR, I believe they rev to around 9-10K RPM.

So yes, the LFA really is up there in terms of RPMs and redline.

TF109B

Yeah, especially for it being a production car. Not many race cars based even on production cars rev that high. LFA is in some rare air. Then again, some cars don't need to rev high, but they don't sound as good as the LFA, so yeah.

05RollaXRS

Yeah, 9500 rpm rev limit is really insane. The best part of it is that LFA produces over 90% of its peak torque over 9000 rpm.

I have seen many 458 Italia dynos and the torque curve begins to fall after 7000 rpm and by 9000 rpm rev limit, it is making only about 75% of its peak torque.

TRDFantasy

Yes, part of the reason why the LFA sounds so unique and so close to an F1 car being the super-high revs. Definitely in some rare company.

Yeah, when I first saw the torque curve for the 1LR engine, I was amazed at just how MUCH torque it produces at 9000 RPM. It's just incredible in terms of how flat the torque remains even at such high revs. Ferrari and Honda's high-revving engines can't even compare. As you partly mentioned, with their engines, the torque starts to drop off between 7000-8000 RPM or so.
